High-Density
Alumina Balls HITO®-92
The HITO®-92 ball is the most widely used ball by our customers, as it is the most efficient ball for a wide range of applications: from grinding clays and feldspars to grinding cements and zirconium sands. The HITO®-92 ball is especially suitable for grinding abrasive and hard raw materials (corundum, silicon carbide, zirconium, feldspars, clinker, glazes, porcelain, etc.) and also when the goal is to achieve fine rejects at the end of the grinding process. Due to its mechanical properties and internal crystalline structure, this type of ball can achieve particle levels of up to 2 microns at the end of the grinding process.
